Quebec Mathematical Sciences Colloquium

In 1925, Tarski posed the problem of whether a disc in R^2 can be partitioned into finitely many pieces which can be rearranged by isometries to form a square of the same area. Unlike the Banach-Tarski paradox in R^3, it can be shown that two Lebesgue measurable sets in R^2 cannot be equidecomposed by isometries unless they have the same measure.

Samples were ground with a Retsch Mixer Mill MM400 for 1 min at 30 Hz and stored at −80 C for subsequent genomic DNA extraction (gDNA). Nicotiana benthamiana stable transformation Nicotiana benthamiana stable transformation was performed following a modification of transformation and in vitro regeneration of the leaf‐disc method (Horsch et al ., 1985 ; McCormick et al ., 1986 ).

An enormous sulfur isotope excursion indicates marine …

The role of ocean anoxia as a cause of the end-Triassic marine mass extinction is widely debated. Here, we present carbonate-associated sulfate δ34S data from sections spanning the Late Triassic–Early Jurassic transition, which document synchronous large positive excursions on a global scale occurring in ~50 thousand years. Biogeochemical modeling demonstrates that this S isotope ...

Spinal Decompression

Spinal decompression therapy is the use of mechanical traction to stretch the spine. Our machine uses a gentle intermittent pull to stretch the muscles around the spine, creates space making space between the vertebrae in the joints of the spine known as the disc. Decompression therapy can be used for disc herniations of the neck […]

Combining modern thermodynamics theory branches, including finite time thermodynamics or entropy generation minimization, constructal theory and entransy theory, with metallurgical process engineering, this paper provides a new exploration on generalized thermodynamic optimization theory for iron and steel production processes. The theoretical core is to thermodynamically optimize performances ...

Big-Data Science in Porous Materials: Materials Genomics …

By combining metal nodes with organic linkers we can potentially synthesize millions of possible metal–organic frameworks (MOFs). The fact that we have so many materials opens many exciting avenues but also create new challenges. We simply have too many materials to be processed using conventional, brute force, methods. In this review, we show that having so many materials allows us …

Multibody system

Introduction The systematic treatment of the dynamic behavior of interconnected bodies has led to a large number of important multibody formalisms in the field of mechanics.The simplest bodies or elements of a multibody system were treated by Newton (free particle) and Euler (rigid body).

 · Fig. 1 shows the design of an industrial stirred bead mill. For example, a similar mill was used in the experimental studies presented in Garcia et al. (2004) or Frances and Anne-Archard (2004).In this type of mill (), the apparent volume of grinding is approximately filled up to 80% with monosized millimetric beads (from 100 μ m to few mm diameter).
